‘Spare-Tire Mode’: Running a VM from a Backup
Smitha backs up the company’s data in daily incremental backups and a weekly synthetic full. He finds that backing up data to the ExaGrid- Veeam solution is quick and efficient. “Our backup windows are short, between three to four hours each night. The ingest speed is much faster than other solutions I work with in the data center,” he said.
ExaGrid writes backups directly to a disk-cache Landing Zone, avoiding inline processing and ensuring the highest possible backup performance, which results in the shortest backup window. Adaptive Deduplication performs deduplication and replication in parallel with backups for a strong recovery point (RPO). As data is being deduplicated to the repository, it can also be replicated to a second ExaGrid site or the public cloud for disaster recovery (DR).
“Using Veeam to restore data from the ExaGrid system is so fast! I’ve actually had to use ExaGrid in ‘spare-tire mode’ where we ran a VM directly from a backup on the landing zone, from the ExaGrid system itself. ExaGrid’s landing zone had been one of the features I was drawn to during the evaluation process, and it ended up being so useful when we needed it. We were able to figure out what caused the problem and restore the program in real time, so there was very minimal downtime for us at that point,” said Smitha.
ExaGrid and Veeam can instantly recover a file or VMware virtual machine by running it directly from the ExaGrid appliance in the event that the file is lost, corrupted or encrypted or the primary storage VM becomes unavailable. This instant recovery is possible because of ExaGrid’s Landing Zone – a high-speed disk cache on the ExaGrid appliance that retains the most recent backups in their complete form. Once the primary storage environment has been brought back to a working state, the VM backed up on the ExaGrid appliance can then be migrated to primary storage for continued operation.
